No problem. Will add construction lines (on a seporate layer) in order for people to easily add drill holes later on.

Here is a model of Corpius`s buffalo shield (added to my warehouse, search for gwise and you will find my models). I will make one more version of this with male headers at the connections instead of the female headers. The Arduino shield headers will remain the same in order to add a secondary shield on top of this.

Edit: the shield can be found here: http://ce-designs.net/in...bs/buffalo-shield-detail

Now the model of the shield has both female and male headers selectable as layers in the model. Will have a look at a BOM for mine and post if others want to go the same route as me. I`ll have a look at the other models now (construction lines). I will leave the layer visible when I upload the models so that you can easily see that the models have been updated. Neutrik connectors have also been uploaded (these are extremely detailed and exact).

I love your work, the Hex head screws are great.

Unfortunately I am not using the same Arduino or shield as I am using the Mega & the itead Studio screen & shield, I may have to draw them myself, bugger :)

I did manage to download a Mega though.

There should be a few mega`s in the warehouse. Beware though quite a few of them are not accurate.

As for my control system. Well most likely I will replace the stacked uno + shield with the piggyback controller that Corpius is working on.

Edit: Placid HD and Placid HDBP bow have construction lines that points to the center of the 4 holes you need to drill.

Love what your doing with the sketchup models Applause

I've been working on the code for the piggyback controller today, but there is still a long way to go.

Thanks. And I love your code work ;)

Have you got the 644 chip allready?

yes I got it and also all other components needed for the controller, but no there was no time to play with it. If there is some time left this week I'll hook it up and give it a go.

Here's something I've been working on today:

Nice!

I am looking forward to hooking up the VFD this week. Exited to see (literally) the display from my listening position. I may need to add a plexi plate in front of my current temporary front plate since I have redesigned the dac and must wait for the chassis to be made when I am done with the design. I dont think it will be up and running in the new case this year, so something less prototype would be nice. A plexi front painted from the rear should do it. That way I get protection for the screen as well. Oh well.

I uploaded a few models today that might be of interest. The IEC inlet from the extended BOM in the integration guide, and XLR`s as well as a BNC passthrough connector (neutrik). I will upload the neutrik rca as well when it is finished. These models are very accurate. Let me know if you find errors in them (PM me).

I am getting closer to a design I like now. It will fit in a bookcase that is 30cm deep with cables connected to the rear panel. Next step is to make the power amp case. Then it`s off to the machine shop :) The front panel will be made by Schaeffer AG (front panel express Europe).

Edit: I did get a bit of a scare when I had a closer look at the VFD. It only has 14pins. However the backlight that is usually pin 15 and 16 is not needed with this display. I will have to use a male/female header system on the io extender so that I will not have to desolder it if it does not work.

Nice design. The display seems larger to me than the 20x4 LCD., but I could be wrong

That is true. I wanted to make it so that I can put the IR reciever next to the VFD. I will perhaps also place the status leds there on the opposite side, but time will tell. I still have some ideas I have to consider and look at. The center of the plaxi plate will allways be the display so I will have to have some extra area on the opposite side of the IR reciever if I want to place it there and not have a seporate hole for it.

I have gone one step further and moved the headphone outputs to one side of the chassis and the rotary encoder to the other (to the side panels). I will use a plexi plate as front and paint it on the rear side and possibly laser etch some logo`s etc.

On other fronts. I have put the VFD and the io extender together and tested it. It was unfortunately not a drop in replacement as I had hoped, so further work on this will have to wait for a second arduino (I need to update the arduino in the dac and I have not made this easy for myself in the current chassis...).

Ooops I have at some point deleted the code that is running in my dac. Wonder if I can download it from the arduino somehow?

Sorry to hear that. I read a post in the Arduino forum that you'd just end up with binary machine instructions, nothing close to what you uploaded to it. But I really don't know.

I think I will have to start over with the code. Not too much work if I can get the right starting point, but I will wait until I get the second arduino so that I can still use the dac with the current control system. I love having a remote ;)

I uploaded some models of hypex UCD, and there are some more to come when I am finished with them.
I also have a model of the Icepower 1000ASP, but that is too large for the sketchup online warehouse, so PM me if you need it.

Thanks. So do you ;)

I hope I get the controller soon :)
